Regarding the regression from the stream, it was caused by the working set size. When the working set size is 2.9G in Prateek's test scenario, there is a regression with task aggregation. If we reduce it to a lower value, say 512MB, the regression disappears. Therefore, we are trying to tweak this by comparing the process's RSS with the L3 cache size. thanks, Chenyu thanks, Chenyu
